Abstract

An aircraft galley cart bay door includes a door main structure having an inwardly facing peripheral inner edge with an inner surface, and a surface seal on the inner surface of the inwardly facing peripheral inner edge of the inner wall. A substantial majority of the main structure of the door is formed from a high strength molded carbon fiber composite material. The door main structure may optionally define a recess, and insulation material can be disposed in the recess defined by the main structure of the door.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS
This application is based upon and claims priority from U.S. Provisional Application No. 61/836,413, filed Jun. 18, 2013, incorporated by reference in its entirety.
This invention relates generally to aircraft catering or galley carts, and more particularly relates to an aircraft galley cart bay door with an inner edge having an inner face with an improved seal construction.
BACKGROUND
On commercial aircraft with in-flight catering services, galley carts are commonly used to transport meals from an aircraft galley to passengers. Such galley carts typically have aluminum door edges that are thermally conductive, and that consequently can interfere with thermal insulation of the galley carts, acting as “cold bridges” in chilled cart bays, for example. Other metal components of the main structure of a door of such conventional galley carts can also to some extent interfere with proper thermal insulation of the galley carts. Such conventional galley cart doors also typically provide a “plug” door seal upon closure by a sweeping action of the door.
It would be desirable to provide an aircraft galley cart bay door that utilizes a carbon fiber reinforced composite material as a major portion of the main structural material of the door to significantly reduce weight and strength of the door, to allow the door to be used for retention of contents of the galley cart as well, and to significantly reduce cold bridging in chilled cart bay galleys through the elimination of metallic components. It would also be desirable to provide an aircraft galley cart bay door that includes an inward facing periphery that allows a compression seal to be achieved, improving and simplifying the sealing, and reducing wear. The present invention meets these and other needs.
SUMMARY OF THE INVENTION
Briefly, and in general terms, the present invention provides for an ultra light weight galley cart bay or compartment door having molded carbon fiber reinforced composite material forming a substantial majority of a main structure of the door, and having an inner edge turned inward to allow a seal to be fitted on an inner face of the inner edge of the door to improve the sealing capability of the door and to reduce seal wear of the door.
Accordingly, the present invention provides for an aircraft galley cart bay door having an inner side and an outer side, the aircraft galley cart bay door including a door main structure having an inner wall with an inwardly facing peripheral inner edge having an inner surface, and a surface seal on the inner surface of the inwardly facing peripheral inner edge of the inner wall. In a presently preferred aspect, a substantial majority of the main structure of the door is formed from a high strength molded carbon fiber composite material. In another presently preferred aspect, the door main structure defines a recess, and insulation material is disposed in the recess defined by the main structure of the door. In another presently preferred aspect, the aircraft galley cart bay door includes a latch located adjacent to an upper end of the aircraft galley cart bay door on the outer wall. In another presently preferred aspect, the inner wall of the aircraft galley cart bay door has an upper shoulder formed along an upper edge of the inner wall, and the latch is located adjacent to the upper shoulder of the inner wall. In another presently preferred aspect, a substantial majority of the door main structure is formed from a high strength molded carbon fiber composite material.
Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments in conjunction with the accompanying drawings, which illustrate, by way of example, the operation of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a rear view of the aircraft galley cart bay door according to the present invention.
FIG. 2 is a front view of the aircraft galley cart bay door of FIG. 1.
FIG. 3 is a side view of the aircraft galley cart bay door of FIG. 1.
FIG. 4 is a top view of the aircraft galley cart bay door of FIG. 1.
 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, which are provided for purposes of illustration and by way of example, the present invention provides for an ultra light weight galley cart bay or compartment door having a main structure that is composed of molded carbon fiber reinforced composite, in which an inner edge of the door is turned inward to allow a seal to be fitted on its inner face to improve its sealing capability and to reduce seal wear.
As is illustrated in FIGS. 1-4, the aircraft galley cart bay door 10 includes an inner side 12 and an outer side 14. A main structure 16 of the door includes an inner wall 18, an outer wall 20, and side edges 22. A substantial majority of the main structure of the door preferably is formed from a high strength molded carbon fiber composite material that reduces the thickness and weight of the door, and allows the door to act as a primary retention device.
An inward facing peripheral inner edge or edge return 24 of the door includes an inner face 26 having a surface seal 28 that allows a compression seal to be achieved, improving and simplifying the sealing capability and reducing wear.
A latch 30 is typically located near an upper end 32 or flange of the door, adjacent to an upper shoulder 34 formed along an upper edge of the inner wall. Insulation material 36 may be incorporated into a recess 38 formed by the main structure of the door.
It should be appreciated that the design of the aircraft galley cart bay door of the invention allows the use of internal concealed hinges, and eliminates the use of bonded aluminum door edges, removing them as cold bridges in chilled cart bays.
It will be apparent from the foregoing that, while particular forms of the invention have been illustrated and described, various modifications can be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
